Nanostack printing for materials research

Leistungen

Layer thickness of >5 different transferred materials tuneable by laser pulse energy

KIT will analyse every new material with respect to the printing results by VSI Especially important will be to define a relation between laser pulse energy and layer thickness of printed material spots Especially we want to find out if indeed the thickness of transferred layers depends on the laser pulse energy or on repeated material transfers onto the same spot

nano3D printer with robot arm functioning for routine printing

The nano3D printer from deliverable D1.1 will be validated by synthesizing arrays of fluorescent molecules.

Donor slides made of > 5 different nanoparticles

In order to provide a hydrophobic shell optionally also for covalently coupling to the surface Lurederra will functionalize nanoparticles Pure organic shells will be used based on organic materials such as oleic acid or polymeric shells For that it is possible to address in two different ways to directly functionalise the nanoparticles in the final DCM solvent or selecting suitable solvents for the functionalisation then recovering the hydrophobic powder and redispersing in the DCM and carrier solution eg SLEC 7552 They will determine the particle size distribution by means of Zsizer and address the grade of hydrophobicity reached Particles are sent to KIT From there they get feedback if these particles can be used for nano3D printing If not TEC and Lurederra will modify the synthesis and functionalisation parameters in order to adjust the properties size and hydrophobicity and will send optimised samples to KITNext KIT will formulate 5 different nanoparticles from TEC and Lurederra into donor slides and transfer them to an acceptor slide

Peptide arrays manufactured with nano3D printer commercialized

As soon as the nano3D printer is available PPP will start to manufacture veryhigh density peptide arrays not funded within the NANOSTACKS proposal and sell these to its customers Money from these sales will be used to further advance the nano3D printer which will be constantly done until the end of the project

Duplicated nano3D printer

Supported by KIT, PPP will duplicate nano3D printer that is shown in Fig. 3. We will re-design the automated loading procedure to speed up the whole process. This will be done with cupping vessels that transport the next donor slide from a parking position to the lasing position, and, at the same time, remove the previous donor slide. A robot arm will then replenish the parking position with another donor slide, while at the same time material transfer is done with the active donor slide.

Reaction chamber for sintering / coupling at defined temperatures available

Manufacturing and testing of a set of gas-tight chambers that will be used to incubate acceptor glass slides with printed nanolayers in a defined atmosphere. Optionally, some of these gas-tight chambers should withstand very high temperature (360°C). We will test this point - might be we don't need that high temperatures.

Donor slides made of > 5 different commercially available chemicals

KIT will formulate >5 different organic materials into donor slides and transfer tehm with the help of the nano3D printer onto an acceptor slide.

Website and project logo

NANOSTACKS website with the domain name wwwNANOSTACKSeu The website will give links to partners ofthe NANOSTACKS project give an idea what we plan to do and gradually from 2023 on will inform visitors aboutpatents and publications that have been generated
